MB89620R Series
s CPU CORE
1. Memory Space
The microcontrollers of the MB89620R series offer a memory space of 64 Kbytes for storing all of I/O, data, and
program areas. The I/O area is located at the lowest address. The data area is provided immediately above the
I/O area. The data area can be divided into register, stack, and direct areas according to the application. The
program area is located at exactly the opposite end, that is, near the highest address. Provide the tables of
interrupt reset vectors and vector call instructions toward the highest address within the program area. The
memory space of the MB89620R series is structured as illustrated below.
Memory Space
*1: The ROM area is an external area depending on the mode.
*2: Since addresses 8000H to 8005H for the MB89P627 and MB89W627 comprise an option area, do not
use this area for the MB89PV620 and MB89627R.
*3: Access to this area is prohibited when using external bus mode.
